Hi! Yesterday, I've upgraded my Retina MacBook Pro 13" Early 2015 to High Sierra final release with clean install. Before that I was using High Sierra GM Candidate since September 12th. I know it's just 24 hours have passed, but here are the issues I encountered: - Very, very bad battery life. I do think Sierra has slightly worse battery life than El Capitan, but High Sierra is a huge step back. I got 5-6 hours of my usage on Sierra, but on High Sierra I only get 3-4 hours. - Graphical glitch while turning on the screen and waking up the device from sleep. - Bonus: FaceTime calling dialog is not movable. I just can't move the window. Anyone see this issues? I might re-install the High Sierra if I am the only one see these issues. Despite having these issues, I do like the High Sierra because of APFS fast cloning files, very smooth animations thanks to Metal 2, and privacy options of Safari. I want to continue using High Sierra, but the issues I mentioned is affecting my usage a lot.
